be1c17c7fd target-i386: fix helper_fscale() wrt softfloat
Use the scalbn softfloat function to implement helper_fscale(). This
fixes corner cases (e.g. NaN) and makes a few more GNU libc math tests
to pass.

326b9e98a3 softfloat: fix float*_scalnb() corner cases
float*_scalnb() were not taking into account all cases. This patch fixes
some corner cases:
- NaN values in input were not properly propagated and the invalid flag
  not correctly raised. Use propagateFloat*NaN() for that.
- NaN or infinite values in input of floatx80_scalnb() were not correctly
  detected due to a typo.
- The sum of exponent and n could overflow, leading to strange results.
  Additionally having int16 defined to int make that happening for a very
  small range of values. Fix that by saturating n to the maximum exponent
  range, and using an explicit wider type if needed.

e2f422047b softfloat: fix floatx80 handling of NaN
The floatx80 format uses an explicit bit that should be taken into account
when converting to and from commonNaN format.

When converting to commonNaN, the explicit bit should be removed if it is
a 1, and a default NaN should be used if it is 0.

When converting from commonNan, the explicit bit should be added.
